U.S. officials called on Monday (February 7) for "concrete action" from China to make good on promises Beijing made to buy $200 billion worth of U.S. goods.

The purchases were supposed to have happened in 2020 and 2021, as part of a so-called "Phase 1" trade deal signed by former President Donald Trump.

The officials said Washington was losing patience with Beijing, which had "not shown real signs" in recent months that it would close the gap in the two-year purchase commitments that expired at the end of last year.

A spokesperson for China's foreign ministry responded on Monday, saying the two sides should work together to resolve conflicts.

"The essence of China-U.S. economic and trade relations is achieving mutual benefit and win-win results, and there are no winners from a trade war."

The agreement, signed by former president Trump in January 2020, defused a nearly three-year trade war between the world's two largest economies.

But the U.S. has since repeatedly called on China to deliver on its promises.

Here's U.S. Trade Representative Katherine Tai in October:

"These are commitments that China made. They are commitments that our businesses, and workers in certain sectors, have looked to. And, we will have to address where this relationship goes from this starting point."

Monday's comments come a day before the U.S. government is due to release full-year trade data that analysts expect to show a significant shortfall in China's pledge to increase purchases of U.S. farm and manufactured goods, energy and services.
